ammonia and at the same time permit .quick escape of the gas as it is generated, thereby overcoming the objections incident tothe ordinary form of coolers in which the gas is carried as a dead weight with the liquid for a considerable distance before the same f Can eSCipe.

Another object of the invention is'to p1 ovide a simple and eiicient cooler which w1ll be effective in use, and which will be economical in the surface required and theresection, partly in elevation, of one form of cooler or device embodying my invention;

and Fig. 2 is a front elevation, partly broken away, of the cooler. l

The casing 10 maybe of any desired form and of any suitable construction, whether of steel, cast iron or otherwiseand at one part of the casing is an inlet 11 for the brine or other medium, and at or near the lower part .of the casing is the outlet 12. The casing 10 is provided with a head 13, and an end or head 14, and extending from the heads 13 and 14 are bafle plates 15 and 16. The plates 15 project inward from the head 14, and one or more plates project inward from the head 13, and these plates are somewhat shorter than the casing, and alternate in ar- Specication of Letters Patent.

rangement so that the brine or medium is caused to pass iirst from one end of the casing to the other and then back again in order to take a circuitous route through said casing, the said balie plates 15 and 16 being inclined if desired to cause the brine or liquid to flow more easily through the casing from the inlet 1l to and through the outlet 12.

Within the casing 1-0 are a plurality of pipes may vary in number and have their inner ends closed and may be made to incline downward as shown, and ,at or near their inner ends may be supported by the bars 18, and their outer ends may extend through the packing glands 19 to form a Itight oint with the head 13, or the said casing in any other shown there are'three pipes arranged in a series, and the Casin I1s shown as holding four independent series of pipes 17. Each pipe may be provided with a flange 2O at its outer end, and the flanges of each series of pipes may be connected to flanges 21 of a common header, device or connection 22.

preferred way. As

pipes may be arranged within the each connected independently to one of the series of pipes 17, and these headers are each provided with aflange 26 which is held toa flange 27 of a tee or other fitting 28. These Fittings 28 are connected by a pipe section 29, which, with a pipe or part 30 forms with the sections 29, and fitting 248, a common pipe or connection, and said section 30 communica'tes with a liquid separator or tank '5 31, the upper part of which is provided wlth an outlet 32 leading to the suction of the usual compressor. By this means, and by having the pipes inclined as shown, the gas as the ammonia boils within the pipes 17, will quickly escape back into the headers 24 and through the pipe 30 into the separator and from there to the compressor.

A pipe 33 leads from the separator 31 to the upper header 22 in order that any liquid separated from the gas will pass from the separator into said connect-ion. This header 22 is provided with an inlet pipe 34C for the ammonia, and in said pipe may be an expanison or other valve 35. The header 22 has an overflow pipe 36 which projects somewhat above the in order that a certain amount of the liquid ammonia may be held therein,

and this pipe lower surface of the header vthe overflow 37 into the header 24, and

- the casing and arrange through the overflow 38 into the header 25. The liquid is thus caused to iow into the different headers and to'be retained therein at auniform height and some of the liquid will be caused to flow into each series of .pipes 17, and by reason of their inclination will give a ra id flow of the saine down the pipes till the iquid reaches the inner closed end thereof, and as the liquid ammonia lwithin the pipes is caused to boil by the brine passing around the pipes, the gases will as read' y and directly escape past the liquid and enter the connections leading to the separator 31.

From the foregoing, it will be seen that a simple cooler is provided which will provide a ra id flow of the liquid ammonia and as rapi an escape of the gas, so that the same will not have to be carried as a dead weight withthe liquid; that the said cooler is simple in construction and may be readily made and assembled; that simple meansare provided whereby the liquid ammonia may be held at a uniform height and may be caused to pass successively to a series of headers independent of each other, and that simple means is rovided whereby the brine'or medium may e caused to pass in a circuitous way throughout substantially the entire length of the casing.

Having thus described my invention, I claim as new and desire to secure by' Letters Patent l. Ina brine cooler, the combination with av casing having inlet and outlet connections for the brine, of baille plates extending lengthwise of the casing to cause the liquid to take a circuitous route therethrough, a plurality of series of ipes extending into d at an Yinclination to cause a liquid to flow downward from one end thereof, a header for each series of pipes, a liquid separator, connections between theseplarator and all of the headers, and means w ereby tli'e liquid ammonia may be caused to pass through one header to another and to retain a uniform height of liquid in each header.
